Embodiment Construction

[0122] The present invention will be further described below in conjunction with the drawings and embodiments.

[0123] Figure 1-Figure 4 Among them, the method of the present invention is:

[0124] A hot and cold rolling load process distribution method, which adopts a single-pass round-trip hot-rolling rough rolling, then six-pass hot-rolling finish rolling, and finally two-pass round-trip cold rolling, which meets the constraints of rolling process factors Under the premise of the constraints of equipment and equipment factors, among the various schemes for distributing the loads of hot rolling, rough rolling, finishing rolling and cold rolling, the particle swarm algorithm is used to obtain the best load distribution scheme. The specific steps are:

[0125] Step 1: Read in the original data, including the steel number and specification of the raw material, the specification of the finished product, the total rolling passes of hot and cold rolling, the rolling temperature of eac...

Abstract

The invention relates to a hot / cold rolling load distribution method. The hot and cold rolling load distribution is comprehensively considered on the premise of meeting steel rolling process constraint and equipment constraint, and the aims of improving the product quality and the production efficiency and saving the production energy consumption are fulfilled. Due to a mode of performing at least once hot rough rolling, performing multiple hot finish rolling and performing multiple cold rolling finally, an optimal load distribution scheme is obtained through a particle swarm algorithm in multiple schemes of distributing loads of the hot rough rolling, finish rolling and cold rolling on the premise of meeting the steel rolling process factor constraint and the equipment constraint.

Description

Technical field [0001] The invention relates to a load distribution method for hot and cold rolling. Background technique [0002] The steel rolling production process is divided into hot tandem rolling and cold rolling. The hot rolling mill and the cold rolling mill are responsible for the production, and the production costs are calculated separately. Considering that most of the strip products produced by the hot rolling mill will be used as raw materials for the cold rolling mill, if the thickness of the finished strip produced by the hot rolling mill is small, the production cost of the hot rolling mill will increase; Large, it will increase the production cost of the cold rolling mill. From the perspective of energy saving, the separation of the cold rolling and hot rolling production processes has caused the unbalanced load distribution of the entire rolling steel, increased production energy consumption, and affected product quality. Therefore, it is necessary to compre...
